OperationalError: "max key length is 3072 bytes" when running tests w/ MySQL w/o migrations

[tuky]

Heyo. I'd like to point out that running tests with MySQL is not working because of the unique=True of registration_id. I know this issue was "fixed" in the migrations. But running migrations while testing is not an option for us (> 1000 migrations). So we deactivate migrations via https://docs.djangoproject.com/en/5.0/ref/settings/#migrate. And that leads to

django.db.utils.OperationalError: (1170, "BLOB/TEXT column 'registration_id' used in key specification without a key length")

Can we therefore set unique=False in the model as well, if the db is mysql? Thx
